4.3.1 Precautions
Before connecting or disconnecting the probe or the cable to the survey meter, make sure that the power
to the instrument is turned OFF.
Connecting or disconnecting the probe or the cable
to the instrument with the instrument power turned
ON may cause damage to the instrument.
There is a potential for shock hazard when the
probe or cable is connected or disconnected from
the instrument when the instrument power is turned
ON. Be careful not to touch high voltage at any
time.
Disconnect the probe from the cable and/or survey instrument prior to any disassembly or reassembly.
4.3.2 Disassembly
The end cap is held onto the main body via an interference fit. Refer to the drawing. The cap may be
forced off by applying a uniform pressure around the edge of the cap in an axially outward direction.
Removing the end cap exposes all of the inner parts. Do
not lose any small pieces. The electrical
connector may be removed by unscrewing it from the main body in a counterclockwise direction.
This does not permit access, however, to all of the inner parts.
4.3.3 Reassembly
The probe may be reassembled by aligning and inserting parts according to their location indicated on the
drawing. The cap may be reattached by applying a compressive force onto the cap in an inward axial
direction, such as with a press. This compresses the o-ring. Make sure that all of the small parts have
been inserted prior to closing the end cap.
The probe should be retested and recalibrated anytime it is disassembled and reassembled. Consult your
local radiation protection program officer for exact instructions.
